June 3- R. H. BEAUMONT CONTROL MEANS FOR A WINDING MACHINE Filed May 21,1930 R m1 My Wm M w m m a M a 7 a M /7 6 FIG 2 Patented June 20, 1933UNITED 1 STATES PATENT OFFICE ROBERT E. BEAUMONT, OF RADNOR,IENNSYLVANIA, ASSIGNOR TO BEAUMONT BIRCH COMPANY, OF PHILADELPHIA,PENNSYLVANIA, A OOH]?ORA'IPIONv VANIA OF PENNSYL- CONTROL MEANS FOR AWINDING MACHINE,

Application filed May 21,

My invention consists in providing control means for a winding machinesuch as is used with drag scrapers. My device consists of a windingmachine of the well-known type,

automatic brakes for the drums of said winding machines and means forcontrolling the clutches which actuate both drums so that it isimpossible that both drums be connected at the same time to the sourceof power.

An added feature of my invention is to provide a ships wheel foractuating the clutches of a winding machine.

For a more complete exposition of my invention reference may be had tothe annexed drawing and specification at the end whereof my inventionwill be specifically pointed out and claimed.

Referring to the drawing, Figure 1 represents a side elevation of awinding machine and a ships wheel controlling the clutches thereof.

Figure 2 represents an elevation of a'modifiecl form of lever forcontrolling the clutches.

In the drawing,

There is disclosed a winding machine of the well-known type which ismerely shown diagrammatically as this apparatus is well known. Thewinding machine consists essentially of a base 1. Mounted thereon are 0winding drums 2 and 3. When the winding machine is operating, one of thedrums is connected to a source of power so as to exert a pull on thecable which is attached thereto but not shown. The other end of thecable is attached to a drag scraper from whence a cable runs to theother drum. It will, therefore, be seen that the drums always turn inthe same direction, one of the drums being connected to a source ofpower to tow the cable while the other drum runs loosely to pay off thecable. The drums are connected to the source of power by clutches orfrictions 44 and 55 which may be of any well-known type. The clutches 44and 55 are adapted to be operated or thrown into clutched or declutchedposition by the arms 4 and 5. On drums of large diameter much pressureis necessary to hold these clutches in engagement. Such pressure cannotbe exerted by a simple lever and it is, therefore,

1930. Serial No. 454,308.

necessary to provide a series or linkage of levers to provide thenecessary pressure. In order to prevent the drum, which is paying offcable and which is, therefore, disengaged from the source of power, fromrunning too freely and, therefore, overrunning' or paying 0d the cablefaster than it is wound up on the drum, which is doing the hauling, itis customary to provide a brake on the drun1 which is paying ofi cable.It is desirable, however, that the drum, which is doing the hauling,shall not be engaged by such a brake. There are, therefore, providedautomatic brakes which .act to engage the drum when it is running in thedirection to pay off cable and to disengage the drum when it is runningin the direction to tow the cable. A suitable type of automatic brake,although other types may be employed, is disclosed in the patent to Hale1,715,003, and in the patent to Beaumont 1,674,586. In the drawing thesebrakes are disclosed as brake bands 6 and 7, band 6 being disengagedfrom drum 2 which is doing the towing while band 7 is engaged to providethe desired amount of friction on drum 3 which is paying off cable.

In order that the necessary power to hold the clutches or frictions,which connect one of the drums with the source of power, may

be conveniently provided manually there is provided a series of levers.These levers are conveniently interlocked so that the clutch of one drumis disengaged when the clutch of the other drum is in engagement or bothclutches may be disengaged. This is shown as consisting of links 8 and 9which are connected to a cross-arm 10, the cross arm being fast on shaft11. Shaft 11 is conveniently mounted in bearings in plate 12 or in anyother suitable manner. There is also fast on shaft 11 segment 13 whichis adapted to be turned by chain 14 from gear 15. Gear 15 is in turnadapted to be actuated from shaft 15 which is mounted in suitablebearings 17 and on which ships wheel 18 is nonrotatably mounted. Links 8and 9 are connected to arms 4 and 5 respectively in such a manner thatwhen one clutch is engaged the other clutch will be disengaged and thatg both clutches may be simultaneously disen aged.

ternate means for actuating arms 4 and 5 and consequently the clutchesconnected thereto are shown in Figure 2. Links 8 and 9 are connected attheir upper ends to crossplate 110,, which is rotatably mounted on shaft11 and which is pivotally sup orted on bearin member 112. Also attac edto cross-member 111 is lever 118 which serves as the actuating member. 7

I do not intend to be limited in the practice of my invention save asthe scope of the prior art and of the attached claim may require.

Iclaim: Control means for a winding machine comprising in combination awinding machine having drums, clutches for. actuating said drums, arms,for actuating said clutches, links for actuating said arms, aninterconnecting member interlocking said links so that both clutchescannot simultaneously be in. engaged position, a means -for actuatingsaidi interconnecting member, and automatic brakes responsive to thedirection: of rotation of said drums and operating in oppositedirections causing one drum to run freely and providing frictionontheother drum.
